We conducted a set of ice-covered delta experiments at the University of Texas at Austin to investigate the changes in delta morphology and associated depositional processes as a result of interaction with ice cover. Please use SEAD SEN collection link to obstain full dataset.

We conducted a set of carbonate experiments in the Chemo-MorphoDynamics (CMD) flume at the University of Texas at Austin to investigate the formation and evolution of a single-thread meander pattern without vegetation. These experiments successfully created a single-thread meandering pattern through chemical processes. Carbonate deposits focused along the channel sides improved the bank stability and made them resistant to erosion, which led to a stream confined in a narrow path. The experimental channels showed lateral migration of the bend through cut bank and point bar deposits. Channel avulsion and chute cutoff were also observed.

We conducted experiments of dunes sitting on a mobile substrate to determine how the ratio of sand to salt thickness controlled dune subsidence. Experiments were conducted in a small tank using PDMS as a proxy for salt. A single dune (a cross-section of a linear dune, as linear dunes were thought to be on top of salt in the Gulf of Mexico) was deposited rapidly on top of the polymer and allowed to subside over time. We have raw time lapse images from two experiments with two different thickness ratios.

These data consist of digitial elevation models of experimental topography recorded at 5 - 10 minute intervals during a series of experiments combining hillslope diffusion and channel incision in a meter-scale eroding landscape. The data were processed from the raw returns of a SICK laser scanner; processing includes noise removal and some interpolation for missing data. DEMs of the steady-state topography for each run are available for download at http://dx.doi.org/10.5967/M09P2ZM3.

Ongoing experiments to develop and validate models for reconstructing paleohydraulics and sediment transport from sandy fluvial cross set strata. Experiments are being conducted in the University of Wyoming Water Resources Facility's 7.3-meter recirculating flume channel.
